Abstract
The utility model provides a circuit breaker anti-interference electricity device comprising a control transformer (1), which is used to convert high voltage AC current into low voltage AC current, and is used to supply a circuit breaker (4) with DC current by a rectifier bridge (2); and a parallely-connected energy storage capacitor (3), which is used to supply the circuit breaker (4) with the power during the occurrence of the interference electricity. The circuit breaker anti-interference electricity device is advantageous in that 1.the internal wiring of the circuit breaker is not required to be changed, and the installation is very convenient; 2.the time delay can be adjusted by the capacity of the energy storage capacitor C; 3.the wiring way is simple, the costs are low, and the reliability is high.
Description
Technical field
The utility model relates to a kind of voltage shock avoiding circuit, belongs to electric equipment protection field.
Background technology
Due to reasons such as thunderbolt, circuit transient faults, distribution system easily produces rolling electricity, shakes in electric process, and system voltage decreases.The no-voltage release of circuit breaker is an electromagnet, and coil losing electricity moment can discharge armature under the drive of spring, then drives tripping mechanism action, and circuit breaker completes trip operation.Shake after electricity, system voltage recovers in time, because low-voltage circuit breaker is without automatic reclosing function, must recover power transmission by manual operation closing by hand.When distribution system is shaken electricity, if no-voltage release can time delay take-off again after several seconds, after system voltage momentary recovery is normal, electric power system is maintained normal power supply, thereby avoid shaking the electric generation that causes power-equipment moment stoppage in transit phenomenon, will greatly reduce system and shake electricity to requiring the impact of the continuous condition of production, reduce economic loss.
Summary of the invention
The problem and shortage existing for above-mentioned prior art, the purpose of this utility model is to provide a kind of voltage shock avoiding circuit, and this circuit can prevent because shaking the electric industrial enterprise's industrial accident causing.
The technical solution of the utility model is: a kind of circuit breaker Anti-electricity dazzling device, comprises a control transformer that High Level AC Voltage is become to low-voltage AC and direct current is provided to circuit breaker through rectifier bridge; When a rolling in parallel is electric simultaneously, be the energy storage capacitor of circuit breaker power supply, wherein the voltage of control transformer is 24V, and the capacity of energy storage capacitor is 1000uF.
While passing through identical direct current and alternating current because of AC coil, suction remains unchanged.Change circuit breaker decompression coil power into DC power supply, an energy storage capacitor in parallel on this coil, when system voltage is too low, electric capacity, from trend circuit breaker decompression releasing winding electric energy, makes it maintain the attracting state of certain hour.In this certain hour, if electric power system can be recovered normally in time, circuit breaker can not trip.
Advantage:
1, need not change circuit breaker back panel wiring, install very convenient;
2, time delay length can be regulated by the amount of capacity of energy storage capacitor C;
3, the mode of connection is simple, and cost is low, and reliability is high.
